摘要:Huanglongbing (citrus greening disease) is a destructive vector-borne disease that affects all varieties of citrus and is currently threatening the existence of the world’s citrus industry. In this talk, I will first briefly introduce mathematical models on citrus Huanglongbing and its control. And then, we will introduce four Huanglongbing models with control strategies, including spraying pesticides to kill psyllid, removing infected tree, cross protection. At last, I will provide a model of ordinary differential equations to model the role of Navel orange and grapefruit in the transmission of Huanglongbing in the Diaphorina citri Kuwayama-citrus cycle. The backward bifurcation conditions are given.
